SELF-LOADING DEVICE FOR CARTt To all n'lmm. it muy concerns' a Be itknown that l, Zl-:Nas \Vnrl'rnnone, of Morton, Delaware county, State ofPennsylvania., have invented an Improvement in Self- 5 Loading Devicesfor (fai-ts, ol' which the followingr is a specilication.

More particularly my invention relates to self-loading devices forcarts, and is shown applied to a street-sweeper of the general rocharacter shown in my Letters Patent No.

730,502, dated June ll, 1903. in which a sweepings-pau arranged closc toa rotating brush is from time to time raised and turned over m dischargethe sweepings into a rceptacle. lnl-hatpatent thehrushamlsweepings-panand their operatin, r devices are formed on and constitute. a part oftile wheeled vehicle which carries the receptacle, the panoperatingdevices heing operated hy thi` rear axle. of the vehicle through themedium of clutch meclamism, which-is` automatically released when thepan has discharged its contents to permit the pan to return.

One of the features of the present invenz5 tion consists in :wrau, iu,,rthe self-loading.;r

mechanism ou a separate. fraaie or truck in dependent of the cart orvehicle which carries the receptacle, to which it may he detachahlyconnected for use and from which it may be disconjiected when the cartis lilled to enahle I the call to he driven olf and its contents to heemptied, while an empty cart may be brought np amlpttachcd to thcself-loading mechanism. 'lhus an attachment may he used with a nnlnhg'i!of carts, and it is unnecessary to carry hack the loading,r devicesevery time a cart is returned to the dumping-ground or elsewhere. f

.While l have shown the dcta'challle truck 4 prm'idcdlwith my improvedself-loadingde- :vices parlicularly applied to instruct-sweeper, l donot mean to limit my invention to this particular application, as thedetachable truck may he provided with suitable self-loading mechanismfor leading a cart with other material-*aa for example, in a hay-loader.

The clutch mechanism for controlling the movcmentsof the loading-pan isarranged on 'the axle-shaft of the wheeled truck with suit- `abledetachable connections for operating it 5 from the ordinary cart.Another part of my invention relates tc the arrangement and manner ofsupporting thev brush or collecting device to enable thc pavemcnt orground to bc swept close to the curb or obstructions and to enable thecollecting device to bc easily raised and lowered to pass Voverobstructions or to suspend the collecting operation.

My invention also embraces improvements 6 in the pan-elevating devicesand in the mechanism for automatically releasing' the clutch to allowthe pan to return after it yhas discharged its contents and to othermprovc ments and combinations of parts, which arc fully set forthhereinafter.

1n thc drawings, Figure 1 is a side elevation of my selfloadingattachment applied to a cart and adapted for street-sweeping. Fig.

2 is a side elevation, on an enlarged scale, of 7o the self-loadingattachmentdetached from the cart. Fig. 3 is a' plan view of the. same.Fig. 4 is a vertical section on thc line A A of Fig.

-3. Fig. 5 is a perspective view cf thc clutch operating mechanism. Fig.6 is a' perspcc- 75 tive view of thc clutch, and Fig. 7 is a sideelevation of the devices for turning the loading-pan.

The self-loading devices and mechanism for elevating the pan todischarge its 'contents 80 may, if desired, be carried by and form apart o the whcclcd vehicle or cart which carries the receptacle. It isto bc understood, thcrcfox-c, that where the tcrn a wheeled frame isused in the claims, unless otherwise limited, i. refers either to thevehicle vcarrying the receptacle or to the separate wheeled truck.

l prefer, however.. to arrangcall of the selfloading devices on a.separate and independent wheeled frame or truck adapted to Ibe attachcdto an ordinary cart. Vl'hen'a cart is lillcd, it may bc detached fromthe sweeping attachment and driven utf;l while the attachment may beapplied to an empty cart.

L is the axle-shaft of thc attachment, to 95 which the wheels L b aresecured. c' is a bracket supported at one end by thc extremity of thcshaft a and at thc other and tents o cart. To more ctl'cctivelydischarge the con- 55 tents, it is desirable to accelerate the motion Q,Y VA'793.700

by ny shaft ai, carrying arms n. a, in the end the shifter jV and throws in vthe clutch. At

of which the brush e is journaled. The brush is driven by the axle-shafta, through suit-. able power-transmitting connections, such as 5 thegear ml' on the axle-shaft a. engaging a gear ai on a counter-shaft m?in the bracket.

(1,'. and a sprocket-wheel im on the shaft :m31 I transmitting motion tothe sprocket-wheel m" on the brush-shaft through the chain m6.

i dri are inclined slide frames or guides carrying at their lower endsboxes d', `in which tbe shaft a2 is journaled. end having upon theirextremitiesan aided:` on which is mounted a small wheel d, running uponthe ground.

I5 The pan m is carried by arms e e olf a rockshaft e', Journalcd inslidesffin the inclined guides d d.

1n the upper ends of the slide-frames d 1l is journaled a shaftg', whichis connected b v v 2O chains or cables g2 with collars e e: on the shafte'. The shaft g' is connected by a chain or cable z' with a sleeve L onthe axle-shaft a, which carries the movable clutch member 'a'.

. The other clutch member i' is fast on the axle- Y 2 5 shaft f1. androtates with it. The clutch member i is controlied by the usualshiftervolte j, pivoted toa cross-har j on the brackets t 1f. carried bythe guides I d.

k is a. short upright rock-shaft journelcd in a bracket k' onthecross-har j and provided at its Iowerend with an arm 1A connected bya'link p' with the shifter-yoke j. (Jn the upper end of the shaft is anerm p2, which carries a laterally-projecting linger q. ar-

3 5 ranged between the' slide-frames (Z d and when projected extendinginto the path of the shaft e'- when it reaches its maximum height. .(See

.'dotted lines in Fig.)

k is an arm on the shaft lli, which is detach- 40 Aably connected in anysuitable manner, as by the chain and rod Ilz, with the operating-lever kon the cart, Fig. 1. f

n is a toothed rack suspended at the top on the shaft g' between theguide-frames (l d l 5:15 and secured at the uottorn to acrosshar nbetween the brackets t t. secured. to said frames.

'n is a toothed gear en the rock-shaft e', adapted when the shaft iselevated in thesliderames Z d to engage the rack u, and therebyv turnthe rock-shaft in its hearings and rock the arms e c and pan minto theposition shown in dotted lines in Fig. 7., when tbe-com, i

f the pan will be discharged into the bar t is provided with jaws t,adapted to renf-the pan a6 itfis turned y For-.this purpose ihe genna-1smade of eccentric form` as:

. shown, and is arranged so that the portion of largest diameter willfirst come' into engagement with the rack.

- the same time the rockingot' the shaft throws the linger q forwardinto the path of the shaft a". The sleeve of the clutch member f beingnow connected with they axle-shaft rotates with it and winds up thechain Il', which unwinding from the shaft (f' rotates that shaft andwinds up the chains y y, lifting the shaft e' in the guides I I andelevating the pan m. 'hen the gear n engages Vthe rack n, the pan isturned. so that on reaching its highest position it turned over to emptythe. contents into the cart. At this time the. shaft f' strikes i thelinger l] and pushes it back. whereby the shaft is rocked back to itsformer position and the clutch i' is released.` The pan-el.,-

' voting mechanism is then disconnected, and

the shaft f' and pan m return by gravity to their normal positions. Tocountcrbalanco the pan and render its descent less sudden, a weight w'may be suspended from the shaft g by a chain lm. so that when the pan islowered the chain w1 will he wound upon the shaft g and will elevate theweight. The weighty" is guided between two vertical guides w12,suspended from a cross-bar w3. carried h v the yw2 is a support Iw,upo'n which thc weight w1 may rest when in its lowest position, so as torelieve the' pan of itz-r counterbalancing effect when thepan iselevated into its highest posithe pan-arms 1 when the pan-trame isturned hack in its descent., and this cross-har is provided with roilcrs/f at the points where it makes Contact with the springs 's'.

cured to the guide-frames fi' a' and forming, with the cross-bars t'j',a truck-franw. adapted to he detachahly connected with thc running-rearof the cart. As shown, the cross- Aceivc a knuckle t on the axle 1 ofthe cart` and chains t" carried hy'the axle, are attached itc pins o nashaft y" l'iracliets 5.2i. By turning the shal't j the chainsmay/be'drawn taut. A ratchet and paw-z secure the shaft againstrotation. To detach the attachment from the cart, it is necessary onlyto turn the shaft j to slacken the chains, detach the chains funn theirpins` and then. detach the chain kl from its rod. l/Vhile thisconstruction for attaching the selfreceive the Contact of a cross-har 5"between' i, journaled in the guide-frames f1' o'. At the end of theguides lOO IIO

tt are rearwardly-extending brackets seloading devices is simple andconvenient. any other suitable devices may be employed for the purposewithout aff ycting the invention.

To enable the brash or collecting device 1 to be raised and lowered, thearms nf 0, which carrv it are joernaled or. the ends ot' the shaft a.and are connected b v chains c7 c with arms r oi' a roch-shaft c.journaled in brackets nl, carried by a frame w, arried by theguideframes (lll. The rock-shaft c is provided with a lever c5,extending over the cart te the drivers seat and adapted to be secured bya chain c". B v depressing the lever c the driver may raise the brush topass over large obstrnctions and when required may secure it in elevatedposition b v the chain e". Owing to the weight of the brush and the armsaan, the lever c may be Comdev-weighed by an adjustable weight s. "itbthis arrangement of the collecting device c in arms nfft on the shaft12, journaled in the guide-frames (l d, the ends of the collectingdevice may be extended at each side to a substantial distance beyond theplane of tbe vehiclewheels. This enables the eci-liecting device to bebrought close to the curb or obstructions while in,operation and in astreet-sweeper permits the pavement to he swept close to the curb oneither side of the street.

To prevent the straining of tne pan m if it should come in contact withthe curb or any other obstruction, l prefer to support it on the arms ae, with provision for end wise move# ment. For this purpose the ends ofthe arms cc terminate in fiat guides ena, which rest against the. backof the pan and are embraced by ears 1f w'j, carried by the pan. Betweenthese ears and the arms 'fare interposed springs c", which tend to holdthe pan in normal/centrai pesition, but permit it to yieldlongitndinaily under strain. As shown. the springs e7 are carried onpins e on the arms e, projecting through the ears f6., :i
